In the related art, when a commodity is customized, a customized image uploaded to a commodity customization interface by a user through a terminal device keeps consistent with the trend of UV (texture coordinate) of a customization area, but in order to ensure that the default direction of the customized image uploaded by the user is consistent with the screen direction of the terminal device, an external rectangular frame of the customization area needs to be parallel to the UV coordinate axis as much as possible when a model is manufactured, otherwise the uploaded customized image is rotated, for example, a vertical customized image uploaded by the user is in the customization area, but the default UV direction of the model customization area is horizontal, the display effect after user mapping is horizontal, a production diagram of the customized image needs to be restored to be horizontal when a factory is generated, and otherwise, a production error can be caused. Moreover, in order to ensure that the frame of the customized area is parallel to the UV coordinate axis, the manufacturing cost of the model is greatly increased, and the manufacturing efficiency of the model is reduced.
In order to reduce the manufacturing cost of the model, improve the manufacturing efficiency of the model and ensure the maximum utilization rate of the UV mapping, a model manufacturer can not consider the direction of a customization area when developing the UV (texture coordinates) so that the customization area can be developed in any direction. For example, fig. 1 is a schematic diagram of a customized model provided by an embodiment of the present invention. If content customization is desired in a customized area (grid area) of a shoe such as that shown in fig. 1, the shoe modeler may deploy the customized area in any direction during UV deployment in order to present as much image information as possible. However, the arbitrary direction spread of the customized region easily causes production errors of the customized image. For example, fig. 2 is a UV expansion diagram of a customized model provided by an embodiment of the present invention, such as a customized area (grid portion) shown in fig. 2, which is developed vertically by a model maker when UV is expanded, but a correct direction of the UV expansion diagram of the customized area should be horizontal, in which case, when the model is customized, a customized image uploaded by a user is vertical, which may cause the customized image direction to rotate along with the UV direction of the customized area after the user uploads the customized image on the customized area, so that a display effect of a vertical customized image on the customized area is horizontal, thereby causing a production error of the customized image.
Fig. 3 is a flowchart of a method for adjusting the orientation of a customized image according to an embodiment of the present invention, where the embodiment of the present invention is applicable to a case where the orientation of the customized image in a customized interface of a product is adjusted, for example, when the method is applied to a C2M mode, where a user performs a product customization phase during ordering a customized product, and adjusts the orientation of the customized image uploaded by the user, the method may be performed by an orientation adjusting apparatus for a customized image, and the apparatus may be composed of hardware and/or software, and may be generally integrated in a terminal device. The device is a device capable of rotating the customized image according to the rotation angle of the UV coordinates of the commodity customized area relative to the screen coordinate system of the terminal device of the scene under the commodity customized scene; therefore, the customized image with the adaptive direction can be obtained, and the customized image is transmitted to the production end after the user places an order for the customizable commodity, so that the customized image on the customizable commodity can be correctly produced when a manufacturer produces the customizable commodity.
In a specific embodiment, the device may be an APP or an applet of an e-commerce platform capable of implementing commodity customization and ordering, or may be another e-commerce platform client capable of implementing commodity customization and ordering.
Here, the terminal device may be any electronic product that can perform human-computer interaction with a user through a keyboard, a touch pad, a touch screen, a remote controller, voice interaction, or a handwriting device, for example, a PC, a mobile phone, a smart phone, a PDA, a wearable device, a palm PC PPC, a wearable device, a tablet computer, a smart television, and the like, and may have an e-commerce platform client installed thereon, which can implement commodity customization and ordering.
It will be understood by those skilled in the art that the terminal device described above is merely exemplary, and other existing or future terminal devices that may be used with the present invention are also included within the scope of the present invention and are hereby incorporated by reference. Here, the terminal device includes an electronic device capable of automatically performing numerical calculation and information processing according to instructions set or stored in advance, and hardware thereof includes, but is not limited to, a microprocessor, an Application Specific Integrated Circuit (ASIC), a programmable gate array (FPGA), a Digital Signal Processor (DSP), an embedded device, and the like.
As shown in fig. 3, the method specifically includes the following steps:
in step 310, in response to the merchandise customization event being triggered, a customized image is displayed in a customization area of the merchandise customization interface.
The customized area is an area which can be changed by a user in the commodity customized model. The commodity customization interface can be used for customizing commodities by users, and commodity images which the users want to customize can be displayed on the commodity customization interface. In the embodiment of the invention, when the commodity customization event is triggered, the customized image is displayed in the customization area of the commodity customization interface, so that the control event of the direction adjustment of the customized image is carried out. Illustratively, when a commodity customization instruction input by a user is received, a characteristic commodity customization event is triggered; when the opening operation of the commodity customization interface is detected, the characteristic commodity customization event is triggered. It should be noted that, in the embodiment of the present invention, the triggering condition of the commodity customization event is not limited.
And responding to the triggering of the commodity customization event, acquiring the customized image, and displaying the customized image in a customization area of the commodity customization interface. The image read from the local photo library may be used as a customized image, an image shot by the terminal device in real time may be used as a customized image, and an image received from another terminal device or a server may be used as a customized image. In an embodiment of the invention, the merchandise customization interface includes a customization area for placing a corresponding customized image.
And step 320, determining the rotation angle of the UV coordinate of the customized area relative to the screen coordinate system of the terminal equipment.
In the embodiment of the present invention, the UV coordinates corresponding to the customized region may or may not coincide with the screen coordinate system of the terminal device. When the UV coordinate corresponding to the customized area is inconsistent with the screen coordinate system of the terminal device, the customized image is rotated according to the UV coordinate of the customized area when the customized image is displayed in the customized area of the commodity customized interface, so that the production error of the customized image is easily caused. In order to avoid production errors of the customized image, the rotation angle of the UV coordinates of the customized area relative to the screen coordinate system of the terminal equipment is determined, so that the customized image can be conveniently rotated according to the rotation angle.
In the embodiment of the present invention, the rotation angle of the UV coordinate of the customized area relative to the screen coordinate system of the terminal device may be understood as a rotation angle of the UV coordinate system corresponding to the customized area relative to the screen coordinate system. Specifically, a UV coordinate system of the customized area and a screen coordinate system of the terminal device are determined, and the rotation angle of the UV coordinate system of the customized area relative to the screen coordinate system of the terminal device is determined according to a unit vector in the U-axis direction in the UV coordinate system and a unit vector in the Y-axis direction in the screen coordinate system. Or, the rotation angle of the UV coordinate of the customized area relative to the screen coordinate system of the terminal device is determined according to the unit vector of the UV coordinate system in the V-axis direction and the unit vector of the screen coordinate system in the X-axis direction. The method for determining the rotation angle of the UV coordinate of the customized area with respect to the screen coordinate system of the terminal device is not limited in the embodiments of the present invention.
And 330, rotating the customized image based on the rotation angle, and taking the rotated customized image as a customized effect graph.
In the embodiment of the invention, the customized image of the customized area in the commodity customization interface is rotated based on the rotation angle, so that the customized image is consistent with the screen direction of the terminal equipment, and the rotated customized image is used as the customized effect picture. The rotation angle includes a rotation angle and a rotation direction. When the customized image is rotated based on the rotation angle, the customized image can be automatically controlled to rotate based on the rotation angle, namely, the customized image is controlled to rotate by the corresponding angle according to the rotation direction. The user may also be guided to manually rotate the custom image based on the angle of rotation.
Optionally, rotating the customized image based on the rotation angle includes: generating rotation prompt information according to the rotation angle; and controlling the customized image to rotate in response to the rotation operation of the user on the customized image based on the rotation prompt information. Specifically, the rotation prompt information may be generated based on the rotation angle, wherein the rotation prompt information may include a voice prompt information and a reference image prompt information of the rotation angle. For example, the voice prompt message may be: "please rotate the customized image 90 ° clockwise", the reference image prompt information of the rotation angle includes the image information corresponding to the rotation angle and the image information corresponding to the rotation reference line. And controlling the customized image to rotate in response to the rotation operation of the user on the customized image based on the rotation prompt information until the direction of the customized image is consistent with the screen direction of the terminal equipment.
For example, fig. 4 is a schematic diagram of a display effect of a customized image in a customized area of a goods customization interface according to an embodiment of the present invention. As shown in fig. 4, since the customized area is a vertical UV developed view in the goods customization interface (i.e. the rotation angle of the UV coordinate of the customized area relative to the screen coordinate of the terminal device is +90 °), when the user uploads the vertical customized image to the terminal device to display the customized image in the customized area of the goods customization interface, the customized image rotates along with the UV direction of the customized area, so that the display effect of a vertical customized image in the customized area is horizontal, and if the customized image is directly printed, the production error of the customized image may be caused. In the embodiment of the invention, the customized image is rotated based on the rotation angle, and the rotated customized image is used as the customized effect graph. For example, fig. 5 is a schematic diagram of a customized image rotation effect provided by an embodiment of the present invention, as shown in fig. 5, firstly, the customized image is in an initial direction, and secondly, the customized image is in a reference direction, that is, the customized image is rotated clockwise by 90 °, so that the initial direction of the customized image is aligned with the reference direction of the customized image, and thus the direction of the customized image is consistent with the direction of the terminal device. Fig. 6 is a schematic view illustrating a display effect of a customized area in a goods customization interface after a customized image is rotated according to an embodiment of the present invention.
According to the direction adjusting method for the customized image, which is provided by the embodiment of the invention, the customized image is displayed on the commodity customization interface in response to the triggering of the commodity customization event; determining a rotation angle of the UV coordinate of the customized area relative to a screen coordinate system of the terminal equipment; and rotating the customized image based on the rotation angle, and taking the rotated customized image as a customized effect graph. By the technical scheme provided by the embodiment of the invention, on the premise of ensuring that the model making cost can be reduced and the model making efficiency is improved, and simultaneously, model making personnel can determine the UV expansion diagram of the model according to the maximum texture utilization rate, the customized image displayed on the commodity customized interface can keep consistent with the screen direction of the terminal equipment, so that the production accuracy of the customized image is effectively ensured.
In some embodiments, determining the rotation angle of the UV coordinates of the customized area with respect to the screen coordinate system of the terminal device comprises: determining a first screen coordinate of a central point of the customization area and a second screen coordinate of a target point; the target point is a deviation point of the central point in the coordinate axis direction of the screen coordinate system, the first screen coordinate is a coordinate of the central point in the screen coordinate system, and the second screen coordinate is a coordinate of the target point in the screen coordinate system; and determining the rotation angle of the UV coordinate of the customized area relative to a screen coordinate system of the terminal equipment according to the first screen coordinate and the second screen coordinate.
For example, the screen coordinate system may be a coordinate system constructed by using a vertex of an upper left corner of a display screen of the terminal device as an origin, an X axis to the right horizontally as a positive direction, and a Y axis vertically downward as the positive direction. In a screen coordinate system, the center point of the customized region is determined, for example, a point selected by human eyes observation of a user can be used as the center point of the customized region, or a circumscribed rectangle of the customized region can be determined, and the center point of the circumscribed rectangle is used as the center point of the customized region. It should be noted that, in the embodiment of the present invention, a determination manner of the central point of the customized area is not limited. Then, the first screen coordinate of the center point of the customization area, that is, the coordinate of the center point of the customization area in the screen coordinate system, is further determined. And taking a deviation point of the central point of the customized area in the coordinate axis direction (the longitudinal axis direction or the transverse axis direction) as a target point, wherein the deviation amount of the target point relative to the central point can be a preset deviation amount. Then, second screen coordinates of the target point, i.e. coordinates of the target point in the screen coordinate system, are determined. Illustratively, the first screen coordinate of the center point C of the customization region is (x1, y1), and the point having the center point at the longitudinal axis with the preset offset L is taken as the target point P, and the second screen coordinate of the target point P is (x2, y2), where x2 is x1, and y2 is y1+ L. Optionally, determining the first screen coordinate of the central point of the customized area and the second screen coordinate of the target point includes: determining a first screen coordinate of a center point of the customization region; and determining a second screen coordinate of the target point according to the first screen coordinate and the screen resolution of the terminal equipment. Illustratively, the first screen coordinate of the center point C of the customized region is (x1, y1), the screen resolution of the terminal device is r, and if the target point P is a deviation point of the center point in the vertical axis direction, the second screen coordinate of the target point P is (x2, y2), where x2 is x1, y2 is y1+ r k, where k is a preset coefficient, and if k is 0.5%, the greater the value of k, the higher the accuracy of the determined UV coordinate of the customized region with respect to the rotation angle of the screen coordinate system of the terminal device is.
In the embodiment of the invention, after the first screen coordinate of the central point of the customized area and the second screen coordinate of the target point are determined, the rotation angle of the UV coordinate of the customized area relative to the screen coordinate system of the terminal equipment is determined according to the first screen coordinate and the second screen coordinate. Optionally, determining a rotation angle of the UV coordinate of the customized area relative to the screen coordinate system of the terminal device according to the first screen coordinate and the second screen coordinate includes: determining a first UV coordinate of the central point according to the first screen coordinate, and determining a second UV coordinate of the target point according to the second screen coordinate; determining a UV vector according to the first UV coordinate and the second UV coordinate; and determining the rotation angle of the UV coordinate of the customized area relative to a screen coordinate system of the terminal equipment according to the UV vector and the reference unit vector. Wherein determining a first UV coordinate of the center point according to the first screen coordinate and determining a second UV coordinate of the target point according to the second screen coordinate comprises: determining a first world coordinate of the central point according to the first screen coordinate, and determining a second world coordinate of the target point according to the second screen coordinate; the first world coordinate is the coordinate of the central point in a world coordinate system, and the second world coordinate is the coordinate of the target point in the world coordinate system; and determining a first UV coordinate of the central point according to the first world coordinate, and determining a second UV coordinate of the target point according to the second world coordinate.
Illustratively, the first world coordinate of the center point is determined according to the first screen coordinate of the center point and the second world coordinate of the target point is determined according to the second screen coordinate of the target point by an openGL algorithm. The first world coordinate is a three-dimensional coordinate of the central point in the three-dimensional world coordinate system, and the second world coordinate is a three-dimensional coordinate of the target point in the three-dimensional world coordinate system. For example, the first world coordinate of the center point C is (x3, y3, z3), and the second world coordinate of the target point P is (x4, y4, z 4). Then, a first UV coordinate Cu () of the center point is determined from first world coordinates (x3, y3, z3) of the center point C in the three-dimensional space, and a second UV coordinate Pu () of the target point P is determined from second world coordinates (x4, y4, z4) of the target point P in the three-dimensional space. The first UV coordinate is a coordinate of the central point under a UV coordinate system, and the second UV coordinate is a coordinate of the target point under the UV coordinate system. From the first UV coordinate Cu () and the second UV coordinate Pu (), a UV vector V0 is determined, wherein V0() -Pu () -Cu (). Illustratively, the rotation angle of the UV coordinates of the customized area with respect to the screen coordinate system of the terminal device is determined according to the UV vector V0 and the reference unit vector V1. Specifically, the rotation angle Φ is determined according to the formula V0 × V1| V0| V1| cos θ, where the rotation angle Φ is θ when the inner product of the UV vector V0 and the reference unit vector V1 is greater than 0, and the rotation angle Φ is 2 pi- θ when the inner product of the UV vector V0 and the reference unit vector V1 is less than 0.
